Turret for turret lathe

Abstract

A turret body is provided with a tool spindle for detachably attaching a complex tool so as to be freely rotated with an axial center as its center. The turret body is provided with indexing means for indexing the tool spindle, and clamping means for clamping the tool spindle at an indexed position indexed by the indexing means. The turret body has a function for indexing the tool spindle for attaching the complex tool thereto and a function for clamping, thereby using the complex tool in a turret lathe.

     5. The turret for turret lathe according to  claim 4 , wherein said indexing means is provided with second means for rotating and driving located at said spindle housing, for freely rotating and driving said tool spindle with said axial center of said tool spindle as its center. 
   
   
     6. The turret for turret lathe according to  claim 5 , wherein said second means for rotating and driving functions as indexing means for indexing said tool spindle by rotation and milling drive means for successively rotating said tool spindle, thereby executing milling machining by said complex tool. 
   
   
     7. The turret for turret lathe according to  claim 5 , wherein said spindle housing is free to be attached to and detached from said turret body. 
   
   
     8. The turret for turret lathe according to  claim 1 , wherein said turret body is provided with a third means for rotating and driving such that said third means for rotating and driving can rotate said tool spindle with said axial center of said tool spindle as its center. 
   
   
     9. The turret for turret lathe according to  claim 8 , wherein said third means for rotating and driving functions as said indexing means, and milling drive means for successively rotating said tool spindle, thereby executing milling machining by said complex tool. 
   
   
     10. A turret for turret lathe, comprising:
 a turret body; 
 a tool spindle for detachably attaching a complex tool, rotatable with an axial center of said tool spindle as its center, provided at said turret body; 
 indexing unit for indexably rotating said tool spindle, provided at said turret body; and 
 clamping unit for clamping said tool spindle at an indexed position indexed by said indexing unit, provided at said turret body. 
 
   
   
     11. The turret for turret lathe according to  claim 10 , wherein said indexing unit has a plurality of engagement portions formed at a periphery of said tool spindle, corresponding to said indexed position, and an actuator for rotating and driving said tool spindle a predetermined angle by engaging with said engagement portion, provided so as to be reciprocated and driven. 
   
   
     12. The turret for turret lathe according to  claim 10 , wherein said clamping unit has a clamp face provided at said actuator so as to freely engage with said engagement portion of said tool spindle. 
   
   
     13. The turret for turret lathe according to  claim 10 , wherein said turret body is provided with first unit for rotating and driving, and a spindle housing for supporting said tool spindle is located so as to be freely rotated and driven with an axial center as its center, orthogonal to an axial center of said tool spindle, by said first unit for rotating and driving.
